Aug 08, 2016 (A Wilson) - The March formation consists of interbedded quartz sandstone, sandy dolostone, and dolostone. The lower contact is the base of the lowermost dolomitic bed, and the upper contact is the top of the uppermost sandy bed. There is a net upward decrease in sand content. Intraformational conglomerate commonly occurs in the lower part of the formation; it consists of clasts of muddy dolostone in a matrix of sandstone or sandy dolostone. The sandstone beds, similar to those of the Nepean Formation, are generally fine- to medium-grained, weather light brown to light yellowish brown, and include both quartz- and calcite-cemented types. The sandy dolostone and dolostone beds are fine crystalline and weather light grey to brownish grey. The sand grains in the sandy dolostone are coarse. All units are thin to thick bedded.
